Ingredients:
7 ounces good dark chocolate (I used Trader Joe's brand)
12 ounces good white chocolate (I used Ghirardelli)
1.5 heaping tsp. yellow bake mix
Colored sprinkles
Directions:
1- Melt the dark chocolate in the microwave, over a double burner, or over low flame. Spread thinly over parchment paper of a silpat.
2- Cool in the freezer for 20 minutes.
3- Melt the white chocolate. Add the cake mix, stir well. Spread over the dark. (Do a little bit at a time because it will melt the chocolate and it won't look as pretty.)
4- Top with rainbow sprinkles. Freeze for 20 more minutes.
5- Break into pieces and keep in the refrigerator until you are ready to eat it.
